Application filed Augusta, 1912. Serial No. 716,502.

To all whom it may concern:

Be it known that I, CHARLES S. BIRD, a citizen of the United States, residing at the town of Walpole, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Shingles, of which the following is a specification. p

The present invention pertains to an improved shingle, the same being composed of waterproof paper and so formed that it may be laid in the same manner as the 0rdnary shingle.

The construction is such that the butt end of the shingle is given the maximum thickness, while the opposite end has the minimum thickness, the construction also being such that a minimum amount of material is used for the surface to be covered.

The invention is shown in the annexed drawings, wherein:

Figure 1 is a perspective view of one form of the shingle as viewed from the under side; Fig. 2a similar view as seen from the upper face; Fig. 3 a like view of a modified form; and Fig. 4, an edge view of a further modified form,

The shingle in the form illustrated and having reference first to Figs. 1 and 2, is composed of two pieces of paper, a relatively long piece folded upon itself and comprising a long upper section 1 and a shorter under section 2, and a second piece 3 lying between and embraced by sections 1 and 2. This produces a shingle having in its butt portion three plies, the end of the butt, designated by 4, presenting an unbroken surface by reason of the fact that it is produced by the folding of a single sheet.

The lamination of the main body of the shingle, which is the part that is'exposed to the weather, produces a structure which is relatively stifl' and which, by reason of the lamination, will not warp. The butt being stiff will not curl or turn up under the action of the wind, and, by reason of the smooth unbroken end, there is no chance of the plies becoming separated either by the action of the wind, or the entrance of water between the plies at the butt end.

The paper of which the shingle is formed is preferably waterproofed. and the various plies are secured together by a suitable cement, preferably asphaltum.

The outer faces of the sections 1 and 2 will preferably, though not necessarily, be treated to a coating of sand or grit, which will be pressed or rolled'into the surface of the shingle to a slight extent.

In Fig. 3 a slightly modifiedform is illust0 trated, the inner or embraced. fly, designated by 3*, being made shorter than the underlying section or ply 2, said ply 2 and the outer long section 1 being of substantially the same proportions as shown in the of them, however, the laminated butt is. present, and the end of the butt is produced 7t by folding a sheet so as to present an unbroken end.

In Fig. 5 a shingle is disclosed produced from a single sheet of paper, the sheet being folded directly back upon itself at the butt W end.

It will be understood that while but three pl es have been shown in Figs. 1 to f incluslve, a greater number may be employed;

so, too, by the use of proper pientsor at paper stock any desired shade or color may be imparted to the shingle.

Having thus described my invention, what I claim is:

1. As anew article of manufacture, a W

paper shingle having its outer face and the butt end of its inner face formed of a single piece of paper folded at the butt end of the shingle to produce an unbroken butt,

and a second piece or ply embraced between at the'folds of the first piece, said second piece and under portion of said first piece ex tending through a limited portion only of the length of the shingle, the various layers or plies being secured together, whereby we there is produced a shingle having a relatively thick, unbroken and strengthened butt.

2. As a new article of manufacture, a

paper shingle having its butt end composed lot of a plurality of superposed plies of paper, the upper and lowermost plies bein formed from a single piece folded at the e d These later constructions give.

the other ply or plies; the end of the lewd two subscribing witnesses. ermost ply extending beyond the embrace ply but terminating short of the upper end CHARLES R 5 of the upper ply,-iand. all of the parts being Witnesses:
